Default Your setup and ignition adv. @ peak torque and redline

I would like to see how much ignition advance others are running at peak torque and redline? I realize that everyone's engine will not have the same VE at every rpm. Post your mod's that affect your engine's air flow (turbo, cams, ported heads, valve size, compression ratio, headers, intake mani, intake diameter, boost pressure, fuel, etc...). I am curious to see how the big turbos with big cams and built engines with different than stock compression are running and what kind of timing advance is required at peak torque and redline (whatever it may be).

EDIT: I know there are a lot of variables to VE.

2011 WRX - 285s on 18x9.5

I was running 17.5 degrees at torque peak (288lbs) and 36 degrees at redline. Max power was 260. 21psi tapering to 15. That's on a 150,000+ mile TD04/2.0L running E85 at 830ft elevation. Stock internals, standard bolt-ons. My motor spun a bearing due to oiling and on teardown had no signs of det.

My new motor is going to be an 8.5-9.0 compression 2.5L with ported 2.0L heads, 272 cams, .5 over valves, stock location GT3071R turbo, and 3" intake/MAF/inlet. I'm interested to see what people put for similar setups.

that's a good amount of timing for a 2.0L! What was your fueling like?

I knew that. It's pretty much 12:1 at full load and leaning towards 12.5:1 at redline.
